Y., a corporationof New York Application July24, 1943, Serial No. 49ers? 12 Claims. (01. 68-253) This inventionrelates to improvements in wringers and more particularly to wringers ofthe type generally associated with domestic washing machines.

Wringers of this type are generally provided with safety mechanisms thatpermit instant releaseof the roll pressure in case of an emergency.Although many different kinds of manually operated release mechanismshave been developed, these mechanisms have not been so designed as to beentirely dependable in an emergency. For instance, some of thesemechanisms have been of such proportions and location as to require awringer operator to exert considerable force in effecting release. Inother structures, the release mechanism, although accessible, has beenso located that the parts thereof deteriorated from an'accumulation ofsoap residue, lint, etc., to such an extent that in an emergency themechanism would not release or, perhaps, release only under applicationof considerable force bythe wringer operator.

To provide an adequate emergency release mechanism for wringers, it isessential that a suitable actuator be so disposed as to be convenientlyaccessible from both sides of the Wringer, and of such proportions as tobe capable of actuation by almost any movable portion of theoperatorsbody, such, for example, as hand, arm, shoulder, etc. Wringer rolls areheld in pressure relationship by means of a strong spring, and in anemergency the release mechanism is tripped to relieve the pressurebetween these rolls. During this relieving movement some partor parts'ofthe wringer must be displaced and these parts frequently take the formof a wringer enclosure or casing. Thus, when the release mechanism isactuated, the roll spring is released with such force and violence thatthe movable parts of the enclosure constitute a, serious hazard to theoperator. This is particularly true when it is considered that therelease mechanism is generally only actuated in an emergency, and undersuch conditions the operator is extremely close to the wringer and isincapable of stepping back or in any other way avoiding these movingparts when they are released. Of course the'purpose of providing movableparts is not only to give space within the wringer enclosure formovement of the roll spring, but also to provide adequate mechanicaladvantage in again placing the spring under tension.

The present invention is directed to the provision of a wringerstructure that, among others, hasfor an object the provision of a safetyroll re- 2 lease mechanism of such proportions and location as to be"capable of instantly releasing the roll spring under any and allconditions of wringer use.

.Another iobj ect :of the invention lies in the provision :of ianactuator .for the release mechanism so located :as to bereadilywaccessible from either side ofithewringervandfso easily?operable that the release mechanism may be tripped by slight movement ofalmost any :partof the body of the operator into contact'withtheactuator.

Another object "of the invention lies in the provision of emu releasemechanism in combination with roll stop means in which the operativepressure oi the rolls is-entirely relieved prior to disconmotion of thedriving means.

Another object-"ofthe invention lies in the provision of a releasemechanism "in which the trip members are 'only indirectly subjected tothe force of the roll pressure means. 7

Another object of the invention will be found in theprovisionofresetmeans for the release mechanismthat is easily operable due toprovision of a high mechanical advantage and at the same time is movablethrough so short a distance as not to constitute ahazardito theoperator.

Another object of the invention lies in the provision ofsa releasemechanism that is operable not I'only to relieve, pressure throughoutthe roll length but to allow the rolls to become displaced andseparablerelative to one another,

A further important object of the invention lies in the provision ofsimplified roll driv connection which .facilitates ready assembly ordisassembly of-a wringer withrespect to the drive head, and in no wayinterferes with or complicates the structure of the release mechanism oractuator for such mechanism.

Thewringerv is carried by a reverse gear housing H which in t urn isswivelable on a drive housing l2. As is conventional, the housing l2extends downwardly 'of oneside' of the washing machine with which thewringer is associated. The wringer l includes a casing I3 having sidewalls 14 and IB, and'an end wall H. The other end of the casing isstyled to blend with the contour of thereverse gear housing H. The sidewalls It and I6 of the casing are fitted with appropriate drain apronsI8 which, in the present disclosure, conceal all but a smallportion ofthe lower roll I 9 as well as the ends of the upper rollZl.

Within the'casing I3 is a frame that includes end uprights 22 and 23.Suitable channels in these uprights position bearing blocks 24 and 24awhich receive the supporting shafts 26 and 26a. of the rolls l9 and 21respectively: In the present disclosure, roll l9 being the driving roll,shaft 26A extends through upright -23- for connection with the drivingmechanism enclosed within the housing ll. A leaf spring'2'l' isprovided, the ends thereof resting uponthe uppermost bearing 'blocks 24,and when pressure is applied through operation of a conventionalconnector 25 and spring tension knob 28, the upper roller 2| is broughtinto desired-pressure relationship with the lower roll l9.

Mounted in the housing II is a reverse drive mechanism, control of whichis had through a lever 29. In its lowermost position this leverdisengages the drive from the rolls and when turned into horizontalposition in either direction, causes the rolls to rotate in onedirection or the other. the roll driveis indicated bythe'shaft 3|supported in a bearing 32.' Set screw 33-, riding in For purposesv ofthe present invention,

a groove in the shaft 3!, prevents axial movement thereof. Although thelever 29 serves to control rotation of the roller drive shaft 3|, anemergency clutch is provided between the shaft 26A and drive shaft 3!.This clutch operates to disengage the roller drive when, in anemergency, a mechanism is actuated to release the spring pressure of therolls. Adjacent its end, shaft 35 is fitted with a drive pin 34'that isreceived within grooves 36 of a clutch sleeve 31. A ring 38 is mountedon this sleeve and serves to position one end of a sleeve encirclingspring 39. The

other end of the spring bears against a throwout collar 4i having anannular groove 42. The collar is prevented from being displaced fromthesleeve by a lock ring 43 but is, however, movable from adjacent thelock ring toward the ring 33, to compress spring 39. A shaft 44 extendstransversely of the housing H, one end projecting beyond the housingwall and being fitted with a reset lever 46.. This shaft mounts athrow-out member 41 for the clutch-above described, which member takesthe form of a pair of arms 46 connected by an integral strap 49. The'lower or free ends of the arms are fi tted with pins 5!) which projectfrom opposite sides into the groove of the clutch collar 41. Remote fromthe strap 49, the member 41 includes identical wing-like extensions, ineach of which is formed an arcuate slot 5|. Between these-ex tensions atrigger member 52 is mounted on and keyed to shaft 44. This memberincludes a central arm 53 that terminates in a trigger finger 54, aswell as a pair of arms 55 which extend substantially at right angles toarm 53. A pin 56 connects the free ends of arms 55 and extendssufi'iciently beyond these arms to project into and through slots 5i ofthe member ii. A spring 51 encircles shaft 44, one end being securedin apart of the framing of the casing II, and the other end engaging one endof the pin 56. The a spring is intended to urge the pin 56 generallydownwardly in the direction suggested by acomparison of Figures 6 and 7of the drawing.

Adjacent the trigger 54, arm 53 is fitted with rollers 58. These rollerscontact the cam edges 59 of a channelled rocker member fillthat formspart of a trip mechanism Bl. The member 60 is pivotally mounted on ashaft 62 and may be centrally positioned by a sleeve or boss 63 on oneside, and a further boss or sleeve. 64 on the other side, together witha spring 66. This spring is so engaged with the member as to urge itinto the tilted position shown in Figure 7. At one end the sides of themember 60 are formed with upturned arms 61. Positioned on the uppersurface of the member is a tilt plate 68 of a size to fit between arms61." One end of this plate extends beyond the end of the member andterminates in an end flange 69, formed with an upwardly opening V-slotthat provides identical cam surfaces H. Adjacent the flange 69 areupstanding arms 10 that align with and are located between arms 61. Theother end of this plate is formed with an aperture 12. Washers 73 seatthe ends of a spring 'l4 An opening 16 is formed in the horizontalportion of the member by bending out a tab that forms an upright 71;This upright projects through the aperture l2, and spring 14, and isfittedwith'springsecuring means 18. Substantially midway of the lengthof the plate 68 is an aperture 19 that aligns with one end of theaperture 16 of the member 66. The size of apertures 16 and I9 is suchthat the trigger 54 may project therethrou'gh. The upturned'arms 67 and16, after mounting plate fiaon'the'll-pp f surf ace of the member; areconnected by a shaft 8L This shaft, together with the arrangement ofspring 14, serves to prevent'displacement of the plate, but at the sametime permit-pivotal move ment with respect to themelnber, i

Attached to the upright 23 of'the frame of the wringer'by a stud 82 is arockerplate 83. i This plate includes arms 84 that extend beyond thesides of the wringer casing and serve to mountcorresponding ends of apair of trip levels or bars 86 located in close "proximity with theupper roll 2|. -A roller 81 is mounted on the upper end of the plate 83and "projects into the V-slotth'at forms cam surfaces 1 I.Asprin'g'fldconnects the shaft of roller 81 with a pin 8'9 ca'rried bythe frame 23. The purpose of spring 88 isto return" the. plate 83 to thevertical position shown in Figure 9, following pivotalmovementthereofinto solidline' position shown either the'dotted orFigure 10; I i

The other end of the wringer casing 13 maybe formed with inwardlyextending bosses"!!! which,

through studs 92, mount the flanged ends 93 of a channel member 94, Thismember extends up-' wardly above the end of the-casing 13. A downwardlydirected extension 910i thecha'nnel member 94 pivotally supports thebase portion of a rocker plate 98 through a pin structure 99. The

plate 98 includes arms Hll that extend in oppoupper edge of housing llandcasing 13 may be flanged or lipped to properly seat the rim I03 ofthe cover. .As shown in the drawing, the member st islocated in theupper portion of the gear housing I I and is centrally, pivotallymounted on shaft 62. The end of this member, remote from' plate 68,engages flanges or arms "I04 of the cover through pin I06 to. providerelative pivotal movement. The other end of the cover includes a pair ofspaced arms 101 that are connectedadjacent their lower ends by pin I08.This pin;

when the release mechanism is set) is engaged with the notches 96 of theside walls of channel lid; pin I03 is a plate I 09, The 'plate is ofa'width This cover extends not only- Between the :arms 'I and attachedto" the to be located between the sides of the channel 5%, being guidedby stop plate 95, and; with the cover I92 in closed position,extendsinto the space between bossesifll, terminating in a cross-headiii. This plate is of a'length to limit upward travel of this end of'thecover-"by striking against stop: plate 95 when the release mechanism hasbeen actuated to relieve pressure of the rolls l9 and 2| '(seeFigure 4i)if 1 f The structure described has contemplated pro vision of paralleltrip levers or bars on eachface' of the wringer and also a mechanismactuated by these bars for upsetting the member 60. The rocker plate 83,being carried :by the wringer upright 23, necessarily forms a part ofthewringer structure, although actually it is a part of the roll pressurerelease mechanism; Under certain circumstancesit may be sound not onlydesirable, but perhaps necessary to assemble the entir roll the 7release mechanism is carried in its en't by the housing l l and when itis desired to mount a wringer, it is merely necessary'to project thepressure-release mechanism within the housing ll and thus enable theinterchangeable mounting or several different-types of' wringers. Fig-Qplate 68 terminates not in an upwardly-opening V-slot but, rather in aflange H Z havin cam surfaces H3. In this structurefthe end oi thehousing "I l is closed by a plate H4 and supported at the upper end ofthis plate is a pin H6. This fpin mounts a rocker plate l-ll thatincludes opposed arms I It extending beyond the side edges offthehousing II and fitted with knobs H9. Rollers I21 "are mounted on therockerfplate H1, one roller contacting each of the cam surfaces Thewringer structure [2-2 of this modification includes an end wall orupright 123, similar to the upright 230i the previous modification; andthe rolls being identical, the lower-roll IS a drive shaft 25A thatextendsbey'ond 'the upright E23. Studs [24, in the upright 12?, areengage-- able with the end plate H 4 of theliousing. Pram the foregoingand examination ofthe drawi'ig pertaining to this modification, it isevident roll shaft itAinto theopen end "of the clutch member and-engagethe studs F24w-ith threaded openingsin theplate H4 "The covert-92 mayormay not include the plate ['09 previously described, but if such plateis attached, the moss head may be swung into place'aft'er mountingthewringer and during closing thefcover'and setting the release mechanism."v 3 To more clearly bring out the featuresiof the present "invention,description "of the assembly, setting, and operation of the structure isas foliows: It will be noted thatthe wringer is first attached to thereverse gear housing H by'placing the end upright 23-against acorrespbn'dingum right of'the housing and securing these uprights bystuds. [as has already been mentioned, the upright 23 of the wringermoulitsrocker plate 83 and'jattendant parts, which include "roller 87.Thus, when the fwringer is positioned, roller 8'? projects into and liesin the base of the V-shaped flange in the inannerindicated in Figures ofthe drawing. Of course simultaneously Withthis asseinbly; thedrive shaft25A is projectedintoand is engaged with clutch sleeve3l. V

For purposes of description, itjm'ay be assumed that the wringer is inoperation, the parts, with the exception of lever 29, being in-theposition shown in Figures 1 and 6. Sheuldfthe operator of thewringerbecomeeaught in anyway, it is mere ly necessary to exertslig'htpressureagainst either of the bars-:86. Such pressure swings rockerplate as and-causes theroller 8'! to bear upon one or the other camsurfaces 11, thus tilting plate 6-2 in such a manner that the trigger54yunder tension' of spring 5?, will move in an are about shaft Mi.Movement of the trigger and arm 53 of which it is a partj turns thereset lever 45 and atthe same time rollers 59 move along the cam edgesas, allowing the member 63 to pivot about its shaft 62. The member,being connectedwi'th the cover li2,receives its pivotal drive from theroll spring 27 which, as isconim'on with wringers, is placed undertension by turning down the conlarly noted that as the member 50 turnsabout its pivotal point, its connection with the cover is such that oneend thereof moves upwardly through an are about the shaft 62, and isthus moved in a lengthwise direction as well. Operation of the mechanismat this point is indicated by the position of the cover in Figure 3 ofthe drawing. 7 Continued turning of the member and endwise movement ofthe cover removes pin I08 from the notches 96, and thus the other end ofthe cover becomes disengaged from the wringer enclosure (see Figure 7).With both ends of the cover freed, said cover is raised at the trip endonly to an extent permitted by the trip member 60, and at the other end,to the extent permitted by the plate I09 (see Figure 4). With the coverin raised position, tension of the roll spring 21 is entirely relieved.During movement of t t igger member 52 from the position of Figure 6 tothat of Figure 7, arms 55 thereof, carrying pin 56, have moved from thetop to the bottom of slots of throw-out member 21 and, with continuedmovement, pin 56 causes movement of the arms to an extent to withdrawthe clutch sleeve 31 from engagement with the drive pin 34. It isthusevident that, as the roll pressure is relieved, the

- emergency clutch is-thrown out and rotation of the rolls ceases.

It has been mentioned that due to the strength of the roll springconsiderable movement of the roll releasing parts is necessary in orderthat a sufficient mechanical advantage may be obtained to reset themechanism and again place the roll spring under proper tension. In thepresent disclosure the wringer cover I02 does not of itself constitute alever by which to reset the roll spring but, rather, by its connectionat one end, through member 60, cam surfaces 59, rollers 58, and arm 53,with the reset lever46, provides such mechanism that an operator of thewringer may, without difliculty, turn the reset lever from the positionof Figure 7 to that of Figure 6. During the resetting operation themember 60 again assumes its substantially horizontal position, thismovement being generally indicated by the dotted and solid lines ofFigure 8. The trigger 54 swings upwardly through slot 19 of plate 68and, because the member has assumed a horizontal position, plate 68likewise assumes such position, spring 14 functioning to assure thismovement. Similarly, the pin 56, carried by arms 55, is moved upwardlyof the slots in the extensions of member 41 and thus causes this memberto move the throw-out collar to increase the tension of spring 39 andthereby urge sleeve 31 into engagement with the drive pin 34.

In the modification shown in Figures 13 to 15 the release and resetmechanism operates in the manner above described. However, it is to benoted that the release mechanism, with the exception of one end of thecover I02, is carried by the housing H. Thus, any of several types ofwringer structures may be utilized with the release and reset mechanismdescribed. In this modification, however, somewhat less facility fortripping the mechanism is provided, since only the knobs H9 serve thispurpose and these knobs are at substantially the point of connection ofthe wringer proper with the housing II. The fact that this modificationprovides a pair of rollers only two forms of his release and resetmechanism for wringers, itwill be understood that variations of thestructure such, for example, as shown in the modification of Figures 13to 15, inclusive, are contemplated insofar as they are within the spiritand scope of the invention as set out in the annexed claims. 1
